Initial commit of bgameboy v000. The source tarball also included empty obj/ and out/ directories which git does not support. byuu says: Project started, so basically everything is new. It's basically a rough skeleton that mimics bsnes project structure. Eventually the src/gameboy folder will be copied into bsnes-official and used by the chip/supergameboy core. The middleware layer (supergameboy/interface) will be merged into a new chip/icd2 folder that will represent direct Super Game Boy emulation in the future. At least, if all goes according to plan. There is a simple GUI that can load ROMs, but do nothing after it. It's not hooked up to ruby yet. There is a basic system class and interface to expose the video/audio/input functions. There is a basic memory bus that doesn't support any MBCs yet. There is a CPU skeleton that only handles easy read/write access to the CPU registers (AF is a really fucked up register.) The core is not hooked up to libco yet, but I intend for it to be, so that I can run the CPU + LCD how I like. If it turns out the LCD+audio is easily enslavable, then I'll probably drop libco and just run it like a regular emulator, using a thread wrapper around it in bsnes only. We'll see. The CPU doesn't actually support any opcodes, and loading a ROM won't actually execute anything.

Update to release v000r01. byuu says: Hooked up a scheduler to enter/exit the CPU core wherever I want. Added basic 4*1024*1024hz clock, and about eleven or so opcodes. Creating the disassembler as I encounter each new opcode, not skipping ahead to do all 'like other' opcodes, eg if I add 'dec b', I don't then add 'dec c' until I encounter it.
